Letters Patent No. 97 ,366, dated .November 3.0, 1869.

The Schedule referred 'to in these `Lettera Patent and making part ofthe same.

To all 'whom it may conce/rn Beit known that I, D. F. DODGE. ofLowville, inthe county of Lewis, and State of New York, have invented. anew and improved Double-Supply Attachment to Pumps; anddo.l hereby'declare that thef0llowing is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and usethesame, reference being had to the accompapying'drawing, forming part ofthis specification. v

Figure 1 represents a vertical longitudinal section of my improveddouble-supply attachment to pumps. Figure 2 is a` Vertical transversesection of the same. Similar letters oi reference indicate correspondingparts. Y

The object of this invention is to provide a device,

by means of which water or other liquid can, from either one of tworeservoirs, be guided to one pump. The invention will be particularlyuseful in households, where the same pump can be used to obtain waterfrom a well and from aicistern, may be desired.

lThe invention consists in the application of a plug within a chamber,which communicates with the suction-pipe of' the pump, Iand with the twosupply-.pipes leading to the two reservoirs. The plug has two aperturesthrough it, either one of which can be brought in communication with thesuction-pipe.l One aperture will connect 'one supply-pipe, and thelother aperture 4the other supply-pipe with the pump. A slight `turn oi'the plug will thereibre serve to bring either the cistcrn orthe wellinto connection with the pump.

A, in thedrmving, 'represents a cylindrical vessel, which has threetubular projections, B, C, and D, each at about right angles to the axisoi' the cyliinlcr. The tubes C and D are preferably on one side, and thetubeB on the opposite side ofthe cylinder.

Within the cylinder is arranged a plug, E, which is iitted into tightpackings, and which has two transverse apertures, a and b, preferably`at right anglesto each other.

A handle, c, is attached to the outer end of the plug. v

In the cylinder may be formed an enlargedchaim ber, d, leading from thetube B to opposite the two tubes O and D.

The tube B is connected with the suction-pipe of the pumps, the tube Cwith a supply-pipe leading to a cistern or other reservoir oi liquid,and the tube D, with a supply-pipe leading to a wel! or other reservoirof liquid.

When the plug is in= the position shown in tig. l,

the aperture u is in line with the tube G and cham ber d, and connects,therciore, the pumps with the cistern, while, at the saine time, theIconnection with the well is entirely closed. The pump can therefore beused to draw water from the cistern. A slight turn of the plug willbringthe zn'n-.lrturc i in line with the tubes l), connecting the pump withthe well, and closint,r the connection with the cistern.

The plug may be conical, as well as cylindrical, and, instead 0i'apertures, it may have grooves or channels, to connectthe suctionpipewith either one ofthe supply-pipes.

The tubular projections ot' the case A may be arranged on thc sameside,- or otherwise placed in suitable manner.

Having thus describeiil my invention, l

` i claim as new, and desire to secure ny ALetters Patentp I The plug F,having two apertures, a. l), and arranged in a case, A, to connecteither one of two supply-pipes with the suction-pipe of a pump,substantially as herein shown and described, and for the purposespocified.
